63. What groups of people in foreign lands gave the most trouble to the Roman Empire?

The Germanic Peoples

Explanation:

The Germanic Peoples, or as the Romans called them, the "Barbarians" were a collection of tribes and peoples that inhabited the territory that is now Germany, North and East of the Rhine, as well as some parts of Eastern Europe and Scandinavia. Some of these people were: the Franks, the Burgundians, the Vandals, the Ostrogoths, the Visigoths, the Angles, and the Jutes.

The Germanic Peoples represented a lot of trouble to the Roman Empire because they lived on the borders of the Roman Empire. They often waged guerrilla wars against the Romans, and entered Imperial land to pillage and loot. With time, some of these people were accepted into Roman society, reaching high military and political positions.

In the end, the Western Roman Empire could not stand the Germanic pressure, and collapsed to the many invasions of Germanic Peoples from almost every point of the Roman Empire.
